<u><em>First, we need to get the amount of change:</em></u>The amount of change can either be an increase or a decrease.
It can be calculated as follows:
amount of change = </span>

<span>
If the amount of change is positive, then it is an increase
If the amount of change is negative, then it is a decrease
<u><em>Then, we need to convert this amount into a percentage:</em></u>Changing the amount into a percentage can simply be done by multiplying this amount by 100
This means that:
% of change = amount of change * 100
<u><em>Combining the two steps:</em></u>% of change = </span>

<span> * 100
<u>Examples:</u>The original price of a certain product was $10. It then became $12. Find the % of increase.
% of change = </span>

<span> = 20%
This means that the price increased by 20%
The temperature decreased from 25 degrees to 20 degrees. Find the percentage of decrease.
% of decrease = </span>

<span> = -20%
This means that the temperature decreased by 20%
Hope this helps :)</span>
Answer:
5 Bags
Step-by-step explanation:
There are 75 carrots and 40 celery sticks.
If we want each bag to have the same combination, the greatest number of bags we can make is determined by the Greatest common divisor of the two numbers.
To find the Greatest common divisor of 70 and 40
<u>Step 1:</u> Express each number as a product of its prime factors
- 40=2 X 2 X 2 X 5
- 75=3 X 5 X 5
<u>Step 2:</u> Pick each pair of common factors.
- 40=2 X 2 X 2 X 5
- 75=3 X 5 X 5
The only factor common to both pairs is 5.
Therefore, the Greatest common divisor of 70 and 40 is 5.
The greatest number of bags that can be made is 5.

- 326.56 inches
- 1959.36 inches
Step-by-step explanation:
<h3>Given</h3>
<h3>To find</h3>
- Travel in 1, 5, 30 rotations
<h3>Solution</h3>
<u>Circumference of the wheel is equal to one full rotation</u>
- C = πd = 3.14*20.8 = 65.312 inches
- 5C = 5*65.312 = 326.56 inches
- 30C = 30*65.312 = 1959.36 inches
